1T5 SYNGENESIA. FRUSTRANEA. 



about the length of the seed. Hab. In open grassy swamps 

 from the maritime parts of Virginia to Florida. Obs. 

 Root small and fibrous, perennial. Stem simple, 1 to o 

 flowered, minutely pubescent, 3 or 4 feet high. Leaves 

 few, upper ones acule, all of them short, about from 1 to 2 

 inches long, and^pxcept the radical ones only 2 or 3 lines 

 wide, very entire. Peduncle enlarged towards the ex- 

 tremity. Calix partly hemispherical, consisting of many 

 series of shortish, imbricated, squarrose leaves Rays ma- 

 ny, neutral, golden-yellow, externally pubescent, dilated 

 towards the extremity, and deeply 3-toothed or partly 

 trifid. Discal florets very numerous, glandularly pubes- 

 cent, 5 or rarely 4-toothed, the base very singularly mdu- 

 ratedand corneous. Anthers bisetose at the base. Stigmas 

 subperfoliate Receptacle corneous, very deeply and re- 

 markably favose so as entirely to include the seed with 

 its pappus! the cells 2 to 3 lines deep; intersections of the 

 "margins toothed. Seed sericeous, inversely conic; leaf- 

 lets of the pappus, linear-oblong, partly acute and entire, 

 connivent in a cylinder, as long as the seed. 



2. * jnnltijiora. Stem branched, many- flowered, smooth 

 and striated; leaves narrow linear, s'lbcarnose and smooth; 

 segments of the calix and tet^-th of the corneous cellular 

 receptacle acuminated; pappus very short, cupulate. Hab. 

 On the sand-hills of the Altamalia, West Florida — Dr. 

 Baldwyn. Obs. Perennial? stem 3 or 4 feet high, terete, 

 considerably branclied above, branches 1 to 4-flowered; 

 flowers fastigiate, pedunculate, terminal. Leaves scatter- 

 ed, sessile, very narmw, often 2 inches long, and scarcely 

 a hue wide, smooth, and somewhat succulent. Hamuli 

 1-flowered; flowers pale yellow, much smaller than the 

 preceding, (about th.e size of those of Anthemis C'otula); 

 branches and smnoth calix glandular; peduncle 3 or 4 

 inches long, angular and grooved, leafy below, (or a con- 

 tinuation of the branchlet.) Calix squarrose, imbricated, 

 segments lanceolate, acuminate, fohaceous. Discal florets 

 4 and 5-toothed, dentures viscidly glandular, base of the 

 lube corneous (as in the preceding). Anthers bisetose at 

 the base. Stigmas long and perfoliate, or enlarged about 

 the middle, smoothish and fusiform beyond.f Receptacle 

 as in the preceding, but the intersections acuminately 

 toothed. Seed immersed, sericeous, inversely and acu- 

 minately conic. Piipjuis paleaceous, much shorter than 

 the seed; leaflets awnless, connivent in the form of a cup. 



f A stigma somewhat similar exists in some species of Core* 

 9psis.
